Rent & eviction protection

Is 3336-3338 Broderick St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

Built 1929
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The Kong Family Trust owns this three-story, two-unit multi-family residential building located at 3336-3338 Broderick Street in San Francisco's Marina neighborhood. Built in 1929, this flats/duplex building has undergone several significant renovations and improvements over the years. Most recently, in 2015-2016, the property underwent substantial ground floor modifications including the construction of a new half bathroom, family room, and study in a previously utilized storage area, with the work being completed at a cost of $32,000. This project was followed by the installation of a new bathroom and laundry facilities, with corresponding electrical work completed in early 2016. In 2015, there was an attempted (but ultimately cancelled) permit application for the legalization of an in-law unit valued at $77,000. Earlier improvements included comprehensive kitchen and bathroom remodels in both 2001 and 1997, valued at $21,000 and $12,000 respectively. The building has also addressed structural concerns, notably repairing a cracked wall following an earthquake in 1989. Recent planning records indicate previous consideration for adding a third dwelling unit under RH-3 zoning, though this proposal was ultimately closed, possibly due to the noted concerns about direct street access and inter-floor connections. Two street-related permits were issued in 2008 for minimal costs, suggesting maintenance of public access areas around the property.

Risk rating

How 3336-3338 Broderick St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
64thpercentile

Out of 988 buildings in this neighborhood, 356 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
